摘要： A process is provided for commissioning a particulate filter for the exhaust system of a device powered in whole or in part by an internal combustion engine. The process improves the filtration efficiency of an uncarbonized or decarbonized particulate filter through a single deposition of metal oxide particles via a gas stream.

摘要： A canister includes a charge port, a purge port, an atmosphere port, a main chamber, a sub chamber, activated carbon, and additional activated carbon. The sub chamber communicates with the main chamber. The atmosphere port is connected to the sub chamber directly or via an additional chamber. The activated carbon is stored in a main volume (Vmain) in the main chamber. The additional activated carbon is stored in a sub volume (Vsub) in the sub chamber. A ratio of a length L in a gas flow direction to an equivalent diameter D in a section perpendicular to the gas flow direction is 2 or more for the sub chamber. A ratio of a volume of the activated carbon stored in the main chamber to a volume of the activated carbon stored in the sub chamber (Vmain/Vsub) is more than 7 and equal to or less than 10.

摘要： A device for injecting water in a vehicle includes a water container which is connected to a number of injection nozzles via a supply line, with a pumping operation for pumping water from the water container to the injection nozzles via the supply line and with a stationary operation in which the supply line is a closed line system. The supply line is equipped with a blocking device which is open in the pumping operation and which is closed in the stationary operation in order to block the supply line and keep same dry. Water is prevented from being suctioned into the supply line and the injection nozzles at low temperatures as a result of a pressure decrease.

摘要： A vaporized fuel treatment device mounted on a vehicle includes a canister configured to adsorb and desorb fuel vaporized in a fuel tank; and a filter case having an air inlet through which air is introduced into the canister. The filter case houses a filter to purify the air. The canister and the filter case are arranged in a wheel well outer edge portion of the vehicle. The filter case is disposed outside with respect to the canister in a vehicle width direction.

摘要： Atomic oxygen is provided for the purpose of promoting reliable ignition and smooth combustion in a spark ignition internal combustion engine is to disperse a low concentration of an atomic oxygen precursor, such as nitrous oxide (N2O), into the flammable mixture of air and gasoline vapor prior to the time of ignition. The introduction of N2O may take place in the intake manifold, in the stream of exhaust gas being returned as part of the EGR process, or directly into the combustion chamber (for example through a small orifice in the base of the spark plug or through a small nozzle located elsewhere in the cylinder head). Introduction of N2O directly into the combustion chamber may be continuous, or it may be pulsed so as to occur at the time of, or shortly before, spark ignition.

摘要： An installation for cleaning a motorization system includes an injector, a diagnostic device, and a controller. The injector executes a cleaning sequence for cleaning the motorization system. It does so by injecting a cleaning fluid into one of the inlets. The diagnostic device determines a soiling level as a function of a defect level. The soiling level is indicative of a level of soiling of the motorization system and the defect level is indicative of a level of defectiveness of the first moving part. The controller is configured to supply cleaning parameters to the injection devices for execution of the cleaning sequence. These cleaning parameters depend on the soiling level.

摘要： A vehicular propulsion system, a vehicular fuel system and a method of producing fuel for an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based reaction chambers to selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced components. Regeneration of an adsorbate takes place through interaction with a solvent, while subsequent separation allows the solvent to be reused. A controller may be used to determine a particular operational condition of the internal combustion engine such that the onboard fuel can be sent to one or more combustion chambers within the internal combustion engine without first passing through the separation unit, or instead to the separation unit in situations where the internal combustion engine may require an octane-rich or cetane-rich mixture.

摘要： Methods and systems are provided for implementing fluid injection through a cylinder valve seat. The engine system may include a cylinder valve with a valve head mating with a valve seat when the valve is closed. The valve seat includes an injection orifice blocked by the valve head when the cylinder valve is closed and unblocked when the cylinder valve is opened.

摘要： A combustion engine having a pair of two-chamber cylinders, in which double ended pistons are located and directed toward themselves oppositely by the angle 180° and compressed together via crankshafts consisting of two crank elements, which are linked rotationally backward by a spacer bearing. The compression is realized with the use of two connecting rod pairs, from which each connecting rod is linked on the one side to with one crank element, whereas the second connecting rod ends are linked to one of shafts, out of which each shaft is connected with one of pistons via a valve rod. In the middle of each cylinder's wall the outlet channel of compressed air is located as well as the outlet channel of products of combustion together with air. In the head of each cylinder and in the compartment the fuel injector, the water vapor injector and the ignition element are located.
